Zirconium diphosphide is a binary inorganic compound of zirconium metal and phosphorus with the chemical formula ZrP₂.^[1]

Preparation

Zirconium diphosphide can be obtained from arc-melting of zirconium with red phosphorus:^[2]

2 Zr + P₄ → 2 ZrP₂

Physical properties

Zirconium diphosphide forms grey crystals that is insoluble in water. Zirconium diphosphide is very toxic.^[3] Has a lead(II) chloride crystal structure.^[4][2][5] It dissolves in warm concentrated sulfuric acid. It decomposes into phosphorus and ZrP when heated in vacuum:^[6]

ZrP₂ → ZrP + P
